What are the main alternatives to String (meetstring.com)?

The realistic alternatives are ShipExtension (self-serve box, rate, and rule automation as an add-on to ShipStation, from $79 per month with optional done-for-you setup), Shipping+ (a self-serve rate-shopping tool with beta pricing from about $25 to $1,000 per month), ShipStation's own native Rate Shopper (included on current plans, but it compares services rather than package types), and staying with String's managed service. Which one fits depends on whether you want the work operated for you or want to own your own configuration, and on how much of the box-plus-rate-plus-documents workflow you need. All figures are as of July 2026.

Is there a cheaper alternative to String?

Yes, several. String is a managed service priced from $1,500 to $2,625 per month billed annually plus a one-time setup fee, as of July 2026. ShipExtension delivers the same class of box, rate, and rule capability self-serve from $79 per month, Shipping+ starts around $25 per month for rate shopping alone, and ShipStation's native Rate Shopper is included on current plans. The trade-off is the model: String builds and operates your rules for you, while the self-serve options mean you (or an optional paid setup) do the configuration.

Do I still need a tool like String if ShipStation has a Rate Shopper?

It depends on your orders. ShipStation's Rate Shopper automatically picks the lowest-cost service, but its own documentation notes it only compares services, not package types, and native SKU rules apply only to single-line-item orders (help articles 4415714484123 and 1260807687290, as of July 2026). If your orders are mostly single-SKU and you already know the box, the native Rate Shopper may be all you need. If a multi-item order needs the right box decided first, or you have multi-SKU rules and retailer packing slips, that's where a tool like ShipExtension or String adds value beyond native Rate Shopper.

How is ShipExtension different from String?

Both cover the same class of box, rate, and rule decisioning, but the model differs. String is a managed service: their team custom-builds and operates your rules for you, at a managed-service price billed annually plus setup, with booking-only sales. ShipExtension is self-serve software you own, from $79 per month, with an optional done-for-you setup layer if you want help. Choose String if you want it fully operated for you; choose ShipExtension if you want to own your rules at software pricing and try it on your own orders first. As of July 2026.

String (meetstring) Alternatives in 2026: An Honest Roundup

Four ways to solve what String solves

String is a managed service that builds and operates your shipping rules for you. If that model or price isn't the right fit, these are the realistic alternatives — and what you give up or gain with each. Pricing and capabilities are as of July 2026.

Self-serve, from $79/mo

ShipExtension

Decides which box a multi-item order fits, rate-shops the lowest-cost eligible service across every carrier account you own, generates retailer packing slips, and keeps a per-order audit trail — as an add-on to ShipStation. Optional done-for-you setup if you want help.

Right pick if: you want String-class box, rate, and rule capability but self-serve, at software pricing, with the option to own your own rules.

Self-serve, ~$25–$1,000/mo

Shipping+

Rate shopping between carriers and services, with package-type conditions. Beta pricing scales by monthly action volume, with a 14-day trial. No multi-item 3D cartonization, retailer packing-slip templates, or weather logic (as of July 2026).

Right pick if: rate shopping is your only gap and you want the lowest entry price for it.

Included on current ShipStation plans

ShipStation's native Rate Shopper

Automatically picks the lowest-cost service — but ShipStation's own docs note it "only compares services. It does not compare different package types." Native SKU rules also apply only to single-line-item orders. The automatic version is on every current plan; the customizable version comes with Standard ($29.99+/mo) and Premium ($349.99+/mo), as of July 2026.

Right pick if: your orders are mostly single-SKU, you already pick your box, and comparing services on that package is all you need.

Managed, $1,500–$2,625/mo annually

Staying with String

String custom-builds and operates your shipping rules for you — "software with an agency feel." Booking-only sales, plus a one-time setup fee, and it publicly names customers including Keto Chow, Giordano's Pizza, and Gains In Bulk (as of July 2026).

Right pick if: you want the work fully operated for you at a managed-service price and you'd rather not touch the configuration.
